Abstract
A system for detecting speech from reverberant signals is disclosed. The system is programmed to receive spectral temporal amplitude data in the modulation frequency domain. The system is programmed to then enhance the spectral temporal amplitude data by reducing reverberation and other noise as well as smoothing based on certain properties of the spectral temporal spectrogram associated with the spectral temporal amplitude data. Next, the system is programmed to compute various features related to the presence of speech based on the enhanced spectral temporal amplitude data and other data in the modulation frequency domain or in the (acoustic) frequency domain. The system is programmed to then determine an extent of speech present in the audio data corresponding to the received spectral temporal amplitude data based on the various features. The system can be programmed to transmit the extent of speech present to an output device.
